What is CP diagram/crease diagram? Why does origami use CP diagram?

In traditional origami, experts like to study crease patterns (CP), which also makes CP patterns look magical and intimidating to novices. This article will take you through the knowledge of CP diagram. I believe that after reading it, you will have a more intuitive and clear understanding.

What is a CP diagram?

If you unfold a completed origami model, you can see a complete CP diagram - a piece of white paper covered with lines. Of course, not all creases will be displayed on the real CP map. Generally, only the creases of a main part of the model will be displayed on it. These creases are also called baselines.

Some origami diagram makers use red lines and blue lines to distinguish valley marks and peak marks. If a CP diagram is very complex, shaded circles will also be used to show key parts of the body.

Why use CP diagram?

Why do some people choose to use CP diagrams when traditional origami diagrams are more convenient? There are four explanations for this issue:

1.CP diagrams are easier to make: just unfold the origami model you have made, and then scan or draw the lines in it, and it is ready. A simple diagram can show all the important folding parts of this model. In contrast, traditional origami diagrams take more time to create.

2. If you want to fold an origami model, but there is no corresponding traditional origami diagram, you can fold it based on the information provided by the CP diagram. In this way, using CP charts is often a helpless move.

3.CP diagrams are very interesting to learn. You can study the crease diagram with great interest, and then try to determine which line corresponds to which part of the origami model. At the very least, you must be able to distinguish the head and body. These are often two obvious areas in CP pictures. If you see short ones that radiate outward from a point, these are often claws, toes or tentacles.

4. At the same time, analyzing CP diagrams can also help you improve existing models or design new models.

Who is using CP charts?

Origami designers often use CP drawings to design new origami models. Using paper and pencil, professional origami designers draw complete origami models using CP drawings.

Because some origami papers do not have corresponding diagrams, people began to use the information in CP diagrams to guide origami making. Anyone can use CP diagrams to make models, but for some complex situations, origami diagrams are more convenient.

CP diagrams are not so easy to use, and it usually takes countless attempts to succeed. Don’t try CP figure origami easily, it requires a lot of skills. Before making complex models, you still need to practice simple origami.
